RCV001879182 | SCV002145468 | uncertain significance | Charcot-Marie-Tooth disease type 2 | 2022-06-13 | criteria provided, single submitter | clinical testing | This sequence change replaces valine, which is neutral and non-polar, with alanine, which is neutral and non-polar, at codon 442 of the LMNA protein (p.Val442Ala). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with muscular dystrophy (PMID: 31069529). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. |
